The Mining Game — the complete manual

What this is

The Mining Game is an NFT mining simulator that pays in real cryptocurrency. You collect component NFTs — cases, processors, GPUs, ASICs, racks — assemble them into rigs, and point those rigs at a mining pool. The pool is backed by a real validator, masternode, or staking node somewhere in the world; whatever that node actually earns is split among the pool's miners in proportion to their rigs' effective power, and paid out on-chain.

Rigs burn WATT as fuel while they mine. Components that are not mining can be staked powered-off to mint WATT by their stake weight. That circle — burn to mine, stake to earn — is the whole economy.

The three eras, and what you own in each

WATT v1 and WATT v2 are the same money at a 1:1 rate — v2 exists because v1 has three uncapped issuance paths baked into an immutable contract and a deployer key nobody can reach. v1 components and v3 components are likewise 1:1, id for id. Nothing you hold is stranded; every path is documented below.

The map — every site and what it does

Set up your wallet

You need one EVM wallet — MetaMask, Rabby, Brave Wallet, Phantom, anything that speaks EIP-1193. The same address works on Polygon and Altcoinchain. WATTxchain and Bitcoin SV are different (see below).

Networks

WATTxchain addresses are different

WATTxchain is a UTXO chain with an EVM layered on top (Qtum lineage). An Ethereum-derived address is valid there but unsignable — the UTXO layer needs a hash160(pubkey) address, not keccak(pubkey)[12:]. Sending an NFT to your MetaMask address on WATTxchain freezes it forever. Use the WATTx wallet extension, the desktop wallet, or the in-game HD wallet, which all derive the correct form.

Bitcoin SV

For the BSV claim you need an ordinals-capable BSV wallet — Yours Wallet is what we test against. Claim to its ordinals address, never a payment address and never an exchange deposit address: rig ordinals sent to an exchange are gone.

The v1 era, briefly

If you played before 2026, everything you own is in one of five places:

1 · Claim staked WATT on Polygon and Altcoinchain

Ending a v1 token stake returns your principal in full plus whatever interest the original owner wallet can still cover. Nothing is locked; the contracts are immutable and still work.

Where token staking actually exists

We verified this on-chain by enumerating every contract the original deployer 0x4B6123e6…bf25 created (contract addresses from CREATE are deterministic, so nonce 0 through 400 can be walked and code-checked one by one). There is no WATT token-staking contract on Altcoinchain. The old UI's Altcoinchain config reuses Polygon's addresses, which have no code there — that is why the Token-staking page shows nothing on ALT. Your ALT WATT v1 is simply in your wallet; skip straight to migration. Altcoinchain does have NFT staking — see step 3.

The Polygon WATT stake — live parameters

How to end a stake

1. Open the classic Token-staking page. stake.mining-game.wattxchange.app/token-staking/ (mirror: the-mining-game.github.io/token-staking/).
2. Connect on Polygon. Chain 137. The page lists your ledger — one row per stake you ever started, each with its own index, amount, start time and accrued gain.
3. End each row you want back. The button calls end(index). One transaction per row; there is no batch. Rows already ended are marked and cannot be ended twice.
4. Check what arrived. A matured end() transfers your principal from the contract and, separately, pulls interest from the owner wallet. If the owner's allowance or balance is short the contract sets interest to zero and still pays your principal — the transaction does not revert.

The LP stake (Polygon only)

A second contract, 0x672654aBeF98d6b1B78c34368072fF294D0339d3, stakes the WPOL / WATT v1 Uniswap-V2 pair token 0xEC54584a…9Bef and pays its interest in WATT. Its parameters are different and they matter:

• maturity 30 days — genuinely enforced.
• penalization 30 % — end before 30 days and you lose 30 % of your LP tokens to the owner wallet, and earn nothing. Check your start date first.
• interest 0 % on the LP token, 125 % / year in WATT — again paid from the owner wallet, and again zeroed rather than reverting if that wallet is short.

The flow is identical: end(index) per row, from the Token-staking page or the explorer.

2 · Claim your holdings on Bitcoin SV

Every rig model, the WATT logo and the full component art are inscribed permanently as 1Sat Ordinals on Bitcoin SV, and WATT plus the five classic rigs exist there as BSV-21 tokens. A snapshot of the EVM chains lets you claim the BSV copies of what you held.

Why this exists

The v1 front-end died because it read its rig list from api.mining.game, a web server on a domain that lapsed. Putting the art on-chain removes that class of failure entirely: 28 MB of GLB models cost about $0.26 to inscribe once on BSV and are served forever by any ordinals gateway. The same 28 MB as EVM calldata would be roughly 483 million gas — impossible.

Why you cannot just be airdropped

A BSV address is derived differently from an EVM address; there is no way to compute the BSV address of a person who holds tokens at 0xabc…. So the claim is a signature proof: you sign a message with your EVM key that names your BSV address, and the service releases from the treasury to the address you signed for. A forged signature recovers to the wrong address and is rejected; a redirected payout changes the message and is rejected.

How to claim

1. Unstake your components first. Staked rigs are owned by the staking contract, so the snapshot credits the contract, not you. Go do step 3, then come back. (The Altcoinchain snapshot was taken at alt@block-6892759; the Polygon one at polygon@block-91012890, 6,645 holders.)
2. Open the claim page. the-mining-game.github.io/bitcoinSV-ALT_claim/ or the Claim-BSV tab on the classic site. The release backend is passed as ?api=<url> and remembered in local storage.
3. Connect your EVM wallet and read your entitlement — WATT plus a quantity of each rig id, straight from the baked-in snapshot. This step is entirely client-side.
4. Paste your BSV ordinals address. In Yours Wallet this is the ordinals address, not the payment ("bsv") address. Never use an exchange deposit address.
5. Sign the claim message with personal_sign. The message binds the snapshot id, your lower-cased EVM address and your BSV address together — change any one of them and the signature no longer verifies.
6. Submit. The service verifies the signature recovers to an address in the snapshot, checks the claimed-ledger so nobody claims twice, and releases BSV-21 WATT and rig tokens from the treasury. WATT converts 18-decimal EVM → 8-decimal BSV at the same face value; rig quantities are preserved exactly.

What you receive

3 · Approve and unstake your v1 NFTs

Your classic components may be escrowed in the old NFT staking contract. Getting them back is a two-step approve-then-unstake, and there is one trap that makes the obvious button fail.

Stake weights are identical on both chains and are the authentic v1 values:

Unstaking, step by step

1. Open the classic NFT-staking page. stake.mining-game.wattxchange.app/nft-staking/. Connect on the chain your rigs are on.
2. Approve the collection — once per chain. ERC-1155 has no per-token allowance; the staking contract needs setApprovalForAll(staker, true) on the collection before it can move anything on your behalf. You did this when you first staked, but if you switched wallets or chains you will need it again. Read isApprovedForAll(you, staker) to check.
3. Withdraw rewards first (optional). withdrawRewards(depositId) per deposit, or getRewardsAmount(depositId) to see what is owed. Do this before unstaking if you want the accrued v1 WATT.
4. Unstake per deposit. unstake(depositId) — one call per deposit record. Use getActivityLogs() or the page's list to find your deposit ids.
5. Confirm the items are back in your wallet with balanceOf(you, id) on the collection, then head to migration or the BSV claim.

4 · Migrate everything to v2

Two independent migrations, both 1:1, both one transaction, both on the chain you are already on. Neither one custodies anything.

Why migrate at all

WATT v1 (Watt.sol) has three uncapped issuance paths welded into an immutable contract: an owner-only mint(), a rewardsMint() callable by any address flagged staking, and a rewardsBurn(from, amount) that lets any gaming-flagged address burn anyone's balance with no allowance. The constructor flagged the deployer as both and never revoked it. That is what let a 2023 exploit inflate supply from a script.

WATT v2 has no owner mint at all. Minting is gated to a MINTER_ROLE allow-list that a multisig rotates and cannot itself use; there is no tax, no blacklist, no pause, no transfer limit, and no burn-someone-else path. It is also a LayerZero OFT, which is what makes the omnichain bridge possible.

A · WATT v1 → WATT v2

Use stake.mining-game.wattxchange.app/swap.html (or the WATT tab on the main stake page).

1. Pick your chain — Polygon or Altcoinchain. The migrator is per-chain; v1 on ALT becomes v2 on ALT.
2. Approve v1 for the WattSwap contract. The page checks your existing allowance first, so a repeat migration skips this.
3. Call migrate(amount). Your v1 is transferred to 0x…dEaD and the same amount of v2 is minted to you. The contract measures the actual balance delta at the dead address rather than trusting the requested amount, so a fee-on-transfer token could never over-mint. v2 can never out-issue v1 because every mint is preceded by a burn.

B · Classic components → v3 components

Use the Migrate old → new tab on stake.mining-game.wattxchange.app.

1. Approve the classic collection for the migrator — one setApprovalForAll per chain. The per-card swap button does this on demand if you skip the explicit button.
2. Swap. Your classic tokens are retired and the same ids and amounts are minted on the new MiningGameItems collection. Swap ALL below does every id you hold in one call.
3. Ids are preserved. id 1 stays the Gaming PC, id 3 stays the XL1 Processor, and so on. The v3 collection simply has 31 more items beyond the original five.

Migrator address, same on Polygon and Altcoinchain: 0x97BcC99ff34FA2cde929c97074011E8929F59679.

Order of operations, if you have everything

1. End your Polygon token/LP stakes → WATT v1 lands in your wallet.
2. Unstake your classic components, one deposit at a time, on each chain.
3. Optional: claim the BSV copies now, while everything is in your wallet and matches the snapshot.
4. Migrate WATT v1 → v2.
5. Swap classic components → v3.
6. Stake the v3 components powered-off, or go build a rig.

The v3 economy

Four contracts carry the whole game, and they live at the same address on Polygon and Altcoinchain — deployed from one fresh key at nonce 0 on both chains, so CREATE produced identical addresses without needing CREATE2.

The rest of the economy, per chain

Where WATT comes from and where it goes

• In: components staked powered off mint WATT continuously, at a rate proportional to their combined stake weight. Claiming costs you nothing but gas.
• Out: a rig that is powered on and mining burns WATT at its components' combined wattConsumption rate, per second. 99 % of that burn is destroyed; 1 % goes to the pool host. There is no staker share and the 99 % is a hard-coded constant no pool can lower.
• Round trip: WATT you spend in the shop is routed into the WattStakingPool via fund(), and WATT stakers share it pro-rata. That pool is a pure redistribution — it has no emission rate of its own, so it pays out exactly as fast as people buy things.

Anti-Sybil, honestly stated

You cannot stop somebody minting from a hundred wallets on-chain. The design makes it unprofitable instead: the free case has ~0 stake weight, the WATT staking pool is funded rather than minted so splitting a stake across wallets earns the same total, and claiming costs gas that exceeds a dust reward. One free PC per wallet, forever, is enforced by a persistent flag that transferring the case away does not reset — that is precisely the bug that was exploited in 2023.

Playing the game

mining-game.wattxchange.app — a single-file 3D game. It installs as a PWA (look for the install chip), works offline for the demo world, and loads every 3D model straight from Bitcoin SV ordinals.

Controls

Menu hotkeys are on the number row because the old letter bindings (W = wallet, S = shop) collided head-on with walking. The on-screen hint fades after your first move.

Demo mode and Live mode are separate worlds

The pill in the HUD toggles between them, and they do not share a save.

A fresh Live world starts empty and then grants you one desk per Gaming PC you own. Demo progress never leaks into Live, and resetting wipes only the world you are in.

The in-game HD payout wallet

Open the Wallet app (5) → MingOS Wallet. It generates or imports a 12-word BIP-39 seed and derives one payout address per payout chain, so you can be paid in coins that have no EVM address at all.

The WTX path matches the WATTx wallet extension and mobile app exactly, so one seed opens the same WTX wallet everywhere. Only addresses and paths are saved in your browser — never keys. Each coin has a SET PAYOUT button that registers the address on the PayoutHub so the pool operator knows where to send your earnings; EVM rewards go to your connected address and need no registration.

Getting components

The free Gaming PC

Every wallet can mint one Gaming PC (item id 1) for free, forever, paying only gas. Use the in-game shop in Live mode, or the Buy components tab on the stake page.

Both chains are open — no allowlist, not paused. The flag is persistent, so transferring the case away does not re-open your mint. That is deliberate: it is the exact hole that was exploited in 2023, when the check was against a live balanceOf.

Buying the rest

The shop sells 36 items for WATT. Tick as many cards as you like, set quantities, and the cart shows a running total, your balance, and what is left after. Cards that would push you past your balance turn red.

Upgrades are endless

Power grid and cooling ladders continue past their 16 published tiers: capacity grows ×1.65 per level, cooling coefficient shrinks ×0.75 per level, and price grows ×2.25 per level. A worst-case farm — 33 rigs of an ASIC plus 19 GPX880s, 41,250 W — is fully powered at power level 18 and fully cooled at cooling level 20. Rack Expansion grows the GPUs a framed rig can hold (8 → 10 → 12 → 14 → 16 → 19); Garage Expansion adds desks.

Powered-off staking — minting WATT

This is the passive side of the economy and the simplest thing to do with components you are not currently using.

1. Open the Stake & Claim tab at stake.mining-game.wattxchange.app.
2. Tick components and set quantities, then Stake selected — or stake one card at a time.
3. Approve on demand. MiningGameV3.stake() takes custody via safeTransferFrom, so the items collection needs setApprovalForAll first. Every stake path now does this automatically; the separate Approve items button is there if you prefer to do it up front. Real stake gas is about 228,000.
4. Claim whenever. claimWatt() pays your accrued WATT; you pay only gas. The hero panel shows pending WATT and your total off-weight live.
5. Unstake per position. Each staked position has its own Unstake button.

Staking WATT itself

The Stake WATT tab stakes WATT v2 into the WattStakingPool and pays you a pro-rata share of every WATT spent in the shop. Unstaking always returns your full principal — rewards are tracked separately and are never at risk. There is no lock and no emission schedule; the pool distributes exactly what has been funded into it.

Mining for real coins

This is the point of the whole thing. A pool is backed by a real node — a validator, a set of masternodes, a staking wallet. Whatever that node earns is reported on-chain and split among the pool's miners by effective power. Payouts are pushed to you automatically; there is no claim button and no gas for you to pay.

How your share is calculated

effectivePower = hashRate × efficiency × 100 / wattConsumption

yourShare = effectivePower(yourRig) / Σ effectivePower(all rigs mining that coin)
wattBurned = duration × wattPerHour / 3600

Only rigs with an active, WATT-fuelled session count toward the denominator. Efficient rigs beat brute-force ones: doubling hash rate while doubling power draw earns you nothing.

Rewards are deposit-driven — there is no emission rate

The v3 engine has no rewardRate. Rewards exist only when real coin arrives via reportPoolDeposit(poolId, targetId, amount), and are split with a MasterChef-style accumulator over effective power. A deposit that arrives while nobody is mining that coin is credited to the host rather than lost. Each coin's accounting is scoped per target, so a host can never discharge one coin's debt with another coin's receipt.

Point a rig at a pool

1. Get a rig NFT. Either mint one (MiningRigNFT, 0.1 POL / 0.1 ALT, random traits) or use the 🎫 CLAIM RIG path, which escrows classic components and derives a rig's traits from them: PC +100 hash/300 W, XL1 +80/200, TX120 +60/250, GP50 +150/400, Genesis Badge adds efficiency, rarity and cooling. reclaim() returns the components.
2. Open the Pool Hub — in the game (3) or on pools.html.
3. Register a payout address for the coin you want. EVM coins pay your connected address directly. For WTX, HTH, BITN or BSV you must call hub.setPayoutAddress(targetId, address) — the in-game wallet's SET PAYOUT button does this, and the game blocks mining until it is set.
4. Choose the coin. A pool offers a menu of payout coins; each rig picks one. The MINE button pops the pool's menu.
5. Start mining. startMining(rigId, poolId, targetId, wattAmount, …) stakes the rig NFT into the pool with WATT as fuel. A minimum of one hour of WATT is required. Your rig's power joins the pool from that moment.
6. Stop when you like. stopMining settles what was consumed, returns the NFT, and pays out. Unused fuel is not consumed.

The live pools

The reference deployment, Genesis Pool, runs four pools on Polygon backed by real infrastructure:

Pool fee 0.5 %. The full miner loop has been proven end-to-end on Polygon mainnet with real money: a real masternode payment of 9.765625 HTH was fed in and split 99.5 / 0.5 exactly between the miner and the pool.

What "payout" actually looks like

The operator daemon polls every 120 seconds. It reads the backing node's real income, calls reportPoolDeposit on-chain (paying the gas itself), and the engine credits each rig by effective power into the PayoutHub as a running balance. A per-coin payer then sends each miner's accrued balance to their registered payout address once it clears the minimum — 0.1 WTX, 1.0 HTH, 1.0 BITN. It is a push model end to end: you never sign anything after starting the session, and you never pay payout gas.

Host a pool — locking 100,000 WATT

Hosting turns your own node's earnings into a game economy. You lock 100,000 WATT v2 once, and from then on you can open pools, set fees, and your own rigs mine for free.

What the stake buys you

• The right to create pools. NodeMiningEngine.createPool checks the PoolRegistry for an active registration with at least the required stake.
• Free mining for your own rigs. A host may call startMining with wattAmount == 0 for rigs they own. The stake is the fuel. Consumption is capped at the deposit, so a zero-deposit session consumes zero forever.
• 1 % of every WATT burn in your pools, with the other 99 % destroyed. That split is a constant — no pool can lower the burn.
• Your reward fee, in basis points, on top.

Becoming a host

1. Get 100,000 WATT v2 on your chosen home chain. Buy on a DEX and migrate, bridge v2 across, or use the supply-ratio mint — depositing WTX mints WATT v2 at the live circulating supply ratio, which is how the reference host funded their stake.
2. Open the Create a pool tab on pools.html, section 1 · Become a host.
3. Fill in your node. Pool name, stratum endpoint, node RPC endpoint, node P2P endpoint, and your fee percent. These are published on-chain so miners can see what they are joining.
4. Register + lock WATT. This approves 100,000 WATT v2 and calls registerPoolWithNode. Your status flips to ACTIVE.
5. Open a pool in section 2: pool name, the payout coins it offers, the node endpoint, your reward fee in bps (300 = 3 %) and your WATT cut in bps. createPool returns the pool id miners will point rigs at.

One pool, a menu of coins

A single 100,000-WATT stake backs a pool that can offer up to 16 payout coins, and each miner picks which one their rig mines. Power, accumulators, deposits and fees are all tracked per (pool, coin) pair. You can extend a live pool's menu at any time with addPoolTarget, and change fees at any time.

Running your pool

Connecting real income

The link between your node and the on-chain pool is the operator daemon (mining-game-pool-operator). There is no on-chain validator field; the daemon holds the mapping and it is the engine's owner or an appointed poolPayer, which is what authorises every reportPoolDeposit. It supports three shapes of income:

Every feeder self-baselines on first sight, so historical balance is never credited — only growth from the moment you wire it up. A delegated field scales credit when you pledge only part of a wallet to the pool. A readChain label lets several addresses on one chain each feed separately, and reportChain lets a node on one chain feed a pool on another.

Stratum endpoints

If your pool takes real miners, publish plain TCP and TLS. Note that a Cloudflare-proxied DNS record blackholes raw TCP — stratum hostnames must be DNS-only A records. TLS is terminated with an nginx stream block; set proxy_timeout 1h, because nginx's 10-minute default drops idle miners mid-shift.

The 100k WATT Club badge

Hosts can mint a fully on-chain ERC-721 badge whose art — roughly 740,000 micro digits rendered as digits made of digits — lives entirely in contract storage across 20 SSTORE2 chunks. No IPFS, no metadata server, nothing that can lapse. One global member-number counter spans every chain, with tiers Genesis #1–100 (gold), Founder #101–1000 (platinum) and Member #1001–10000 (electric), and live Stake Chain and Pool ID traits. Mint at nft.wattxchange.app/genesis.html.

All six verify the same genesis art hash 0x9b7563e1…3906cf on-chain. The series genesis is WATTxchain, where mint payments auto-stake in the treasury.

Closing a pool

Unstaking is a 30-day hold, and the pool keeps running the whole time.

1. Request unstake. Your registration moves to UNSTAKING. You can no longer create new pools, but your stake stays locked and therefore your existing pools stay backed — and you keep mining free.
2. The warning is public. poolShutdown(poolId) returns (shuttingDown, unlockAt), and every front-end shows miners a countdown so they can move their rigs before the pool goes.
3. Complete after 30 days. completeUnstake returns your 100,000 WATT. Only then does enforceRegistration(poolId) become callable — by anyone — to deactivate the pool.

PAUSED is different from UNSTAKING: a paused host still counts as staked and keeps their pools; re-activation re-checks the stake.

The bridges — five rails, one map

The game spans four chains with three completely different address formats, so there is no single bridge. There are five rails, each honest about its own trust model.

WATT omnichain — LayerZero Live

Move WATT v2 between Altcoinchain and Polygon. WATT is burned on the source chain and minted on the destination — the same token, the same total supply, 1:1. No wrapped IOU.

Use it: stake.mining-game.wattxchange.app/bridge.html

Why we self-host the mesh

LayerZero's official endpoints only route to endpoint ids that LayerZero Labs has registered, and the registration functions are owner-only, so Altcoinchain cannot use an official endpoint on any remote chain. We therefore run our own EndpointV2 + SendUln302 + ReceiveUln302 on both ends, with eid == chainid. The adapter subclasses OFTCore directly: _debit is burnFrom, _credit is mint, and the adapter holds MINTER_ROLE on WATT v2 on each chain.

Sending

1. Pick a direction and connect on the source chain.
2. Enter an amount. The page quantises it for you — see the warning below.
3. Approve WATT v2 for the adapter, then Send. Messaging fee is currently 0.
4. Wait for the relayer. ALT → Polygon needs 40 Polygon confirmations, so about twenty minutes. Polygon → ALT needs 6 and lands in seconds. Send gas is roughly 133,000.

WATT ⇄ WTX desk Live

Use it: bridge.wattxchange.app — the desk serves its own swap UI, so there is no separate front-end to go stale.

This is a desk, not an atomic swap, and that is a consequence of the chain. Users cannot sign transactions on WATTxchain's EVM — its MetaMask compatibility layer recovers the sender and then dispatches node-wallet RPCs — so WTX has to move on the UTXO layer.

How a swap runs

Vault 0x54117CAd2835B3D5B499f3acA03B1Ff643Af1955, same address on Altcoinchain and Polygon. Operator 0xE731A3d4D7C5cb642B5041392a4Eb6E966Dba11a.

Two pricing modes

Virtual AMM (default)

A constant-product curve over the desk's actual aggregate reserves — the WTX float on one side, the operator's WATT across every enabled EVM chain plus the BSV treasury on the other: out = R_out × in / (R_in + in). A fixed 1:1 rate was drainable the moment WATT's market price diverged from one WTX, so the pool self-prices instead. Reserves are read live with a 10-second cache and the desk fails closed — an unreadable reserve queues the swap rather than mispricing it.

Supply-ratio mint (WTX → WATT)

Instead of paying from float, the desk can mint WATT v2 at the live ratio of circulating supplies (WATT circulating ÷ WTX circulating), sourced from the supply aggregator with a 30-minute staleness gate. This is how the reference host funded their 100,000-WATT stake — one 18,500 WTX deposit minted 85,584 WATT. The cap is 100,000 WTX per swap.

WATT cross-EVM (desk) Live

The same desk also moves WATT v2 between Altcoinchain and Polygon at 1:1 minus fee, paid out of the operator's float rather than by burn-and-mint. You lock on the source chain, the desk pays on the destination from float, then claims your lock.

This exists alongside the LayerZero rail because it settles in seconds in both directions and needs no messaging confirmations. Its depth is bounded by float — currently a few hundred WATT per chain — so the LayerZero bridge is the right rail for large amounts and the desk is the right rail for small, fast ones. Both are reachable from the same bridge page and the desk UI.

ALT omnichain Live

Native ALT moves to Polygon as an ERC-20 over the same LayerZero mesh, using a lockbox rather than burn-and-mint (you cannot burn a native coin).

Backing is exact: escrow balance always equals the Polygon-side total supply. Proven both ways on mainnet. ALT → Polygon needs 40 confirmations (about 20 minutes at ALT's ~30-second blocks); the reverse needs 6.

Bitcoin SV attested bridge

Bitcoin SV has no EVM, so the v3 Solidity cannot deploy there. The BSV leg is a burn-and-attest design with a deliberately bounded trust model.

• Exit is trustless. You burn WATT v2 or components to 0x…dEaD through MiningGameBridgeOut, which emits WattExited / NftExited with a bridgeId = keccak(chainid, bridgeOut, nonce) — unique across chains and replay-proof. The oracle can only ever attest to a real, already-final on-chain burn, and it has no power to mint on the EVM side.
• Release is bounded. The BSV treasury is a fixed pre-mint of 10,000,000 WATT with an n-of-m quorum signing releases. The worst an oracle failure can do is leak up to the treasury — it can never mint infinitely and it can never take your coins. That trade-off was chosen explicitly.
• Coming back uses the mirror-image MiningGameBridgeIn, an n-of-m quorum that mintBatches on the destination. Its digest commits to the destination chain id, the bridge contract, the bridge id, the source chain, the source bridge-out contract, the recipient and the exact ids and amounts, so a signature cannot be replayed on another chain or redirected. Signers must arrive strictly ascending, which is an O(n) duplicate defence with no storage. The emergency stop is revoking its minter rights, beyond the ordinary pause().

The one-way EVM → BSV path most people want is the signature-proof claim, which is simpler and already live.

Route finder — every rail at once

The desk exposes a route engine that quotes multi-hop paths across all rails: QuickSwap WATT v2/WPOL, SwapinDEX WATT/wALT on Altcoinchain, the WattSwap v1→v2 migration, the desk's cross-EVM lane, the desk's WATT⇄WTX lane, and the LayerZero ALT bridge.

GET https://bridge.wattxchange.app/api/route?from=WTX&to=POL&amount=100
GET https://bridge.wattxchange.app/api/quote?direction=WTX_TO_WATT&amount=100&dest=0x…
GET https://bridge.wattxchange.app/api/prices
GET https://bridge.wattxchange.app/api/info

The response gives the best path with per-leg venues, amounts and caps — or a blocked[] list naming the exact missing pool. The game's SELL popup uses this: it shows a live routed quote, a leg map, and jump-off buttons, and it greys out pairs it cannot route.

Reference — all contracts

Same address on every EVM chain

Polygon 137

Altcoinchain 2330

WATTxchain 22356

Reference — component catalogue

All 36 shop items with their on-chain traits. Hash is hash rate, W is WATT consumption per hour, SW is stake weight (what powered-off staking pays on), Eff is efficiency, Luck biases block finds.

Ids 1–5 are the original v1 components and migrate 1:1 from the classic collection. Beyond level 8, power and cooling ladders continue indefinitely — see Upgrades are endless.

Reference — payout targets and algorithms

Payout targets are registered on the PayoutHub at runtime, not compiled in. That is the change that made PoS chains and masternodes possible at all — neither is reachable by a mining algorithm, so the payout target comes from the pool you chose, not from your rig's algorithm trait. Traits still decide how much.

Ids are fixed and the game hard-codes them, so they are stable. A pool may pin one algorithm or accept any (ANY_ALGO = 255, the normal setting for PoS and masternode pools).

Troubleshooting

"Connect Wallet does nothing — no popup, no error"

Brave Shields blocking a script or RPC host. All page logic lives inside one ES module; if any import in it is blocked, the module never executes, so the button exists with no handler attached and clicking it is silently inert. It reads exactly like a wallet bug and is not one. Drop Shields to standard for the site and reload.

"Component cards show flat pictures instead of 3D models"

WebGL is unavailable — usually Brave's fingerprinting protection on Strict rather than a hardware problem. The pre-rendered 512 px stills are the intended fallback, taken from the same on-chain models with the same camera and lighting. Without WebGL the page also skips the multi-megabyte GLB downloads entirely, so it is faster.

"Stake failed: execution reverted (unknown custom error)"

Almost always ERC1155MissingApprovalForAll (selector 0xe237d922) — the staking contract takes custody and needs setApprovalForAll first. Every stake path approves on demand now, but an older tab will not. Reload, or press Approve items.

"The bridge rejects my MAX amount"

SlippageExceeded. Quantise to 6 decimals — see the 6-decimal trap.

"contract runner does not support sending transactions"

A read-only contract handle was used for a write. If you see this on our pages, tell us — it is a bug on our side, not yours, and it has bitten us twice (unstake and one liquidity path).

"gas price below minimum: gas tip cap 1500000000, minimum needed 25000000000"

Polygon enforces a 25 gwei priority-fee floor and some libraries default to 1.5 gwei. Set maxPriorityFeePerGas to at least 30 gwei.

"could not coalesce error" on Altcoinchain

Altcoinchain's node does not like EIP-1559 fee data from some wallets. Use legacy (type-0) transactions with an explicit gasPrice. Our pages force this automatically.

"My swap is stuck at 'waiting for your deposit'"

Check the amber banner. If WATTxchain has stopped producing blocks your deposit cannot reach three confirmations, and the desk waits rather than paying. Funds are safe and refundable throughout, and the desk pays automatically the moment blocks resume.

"My garage is empty but I own components"

They are staked. Escrowed items are owned by the staking contract, so balanceOf cannot see them. Open the wallet panel's STAKED COMPONENTS section and unstake what you want to build with.

"I upgraded and my wallet never prompted me"

Either you have game credit (that is the point of it — one signature up front, then no prompts), or you are on a stale tab from an older build spending simulated WATT. Hard-reload and check the credit banner.

"The free-mint button reverts with 'not for sale'"

Old build. The free case is minted by CaseFreeMint, not by the shop. Use the current site.

"WATT sent to the staking pool never showed up"

A plain transfer strands it. The pool only counts fund(amount).

Pages look stale after an update

GitHub Pages caches for up to ten minutes. Hard-reload (Ctrl/Cmd + Shift + R).
